Specification of Letters Patent.

To all whom it may concern:

Be it known that I, citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York,have invented new and useful Improvements in Door-Hangers, of which the following is a specification.

This invention relates to door hangers, and has special reference to door hangers for. supporting and operating heavy sliding doors.

The invention has for its object to provide a door hanger with a roller deviceso constructed and mounted as to operate with a minimum of friction and prevent amming-of the door at any place on the rail from which the door .is suspended. The invention consists of a han or frame embodying a novel form of re ler, constructed and arranged as hereinafter set forth "and claimed.

Referring to, the drawing, Figure l, is a vertical transversev sectional view of the door hanger mounted in position for use;

Fig. 2, is a perspective view of the roller and Fig. 3 is {similar view with the segments of the roller separated to showthe interior construction more clearly; and Fig. 4 is a detail view of a portion of the bracket.

In carrying out my invention a bracket 1 is secured to the top of the door 16 and projects above the same. The bracket comprises base plate 2 provided with vertical sides 3, 3 and an arched top. Mounted in the sides 3, near the arched top, in the threaded holes 4, 4, are laterally projecting pivot pins 5, 5, extending interiorly of the" hanger frame. These pins are provided at their inner ends with cone-shaped bearingpoints (3,6, and the bodies of thepins are screwhreaded and adaptedto-be inserted in the said holes 4., 4, and to be adjusted laterally with relation to the roller "7 which is journaled on said pins. Conical recesses 8, 8, are provided at diametrically disposed points of the roller, to receive the points of the said pins. Set screws 9, 9, which project through the edges of the sides 3, 3 and contact with the bodies of pins 5, 5, are provided for the purpose of securing the latter against movement when properly adjusted. "The roller 7 is preferably cylindrical in form and is made of segments, in this case three being shown. 'Jlhese segments, 10 11 and 12 are spaced 2.,art to prevent fric- CHARLES O. MARX, a,

.a plurality of segments, one of which tionaljcontact, by the interposition of 13, of suitable size and numbenarranged in registering, circular, concaved tracks 14, formed in the opposing faces of the segments-of the roller. The segments are arranged to revolve on a common horizontal axis, alined with the journal pins 5, 5.

.The track or rail 17 which is secured to the door frame, is located inside of the bracket l, and the central segment 11 of. the roller 7 travels on the upper edge thereof. The upper edge is conb'aved to prevent the roller from leaving the track.

Of course it will be understood that it isusual to employ a set of door hangers, which comprises two.

When constructed asabove described, with all friction reduced to ajr'n-inimum, the movement of the door on the track is smooth and it does n0t,;:jam. This latter fault is usually the result ofderailment.

The principal objections to sliding doors of the heavier type, are the noise and difii-.

signed to operate on the doortrack, antifriction means interposed between the-sections of the roller for retaining the said central section in juxtaposition with 1 the other sections, and studs, mounted in the bracket, on which the end-sections of the roller are journaled axially.

In a door hanger, the combination with a bracket, of a ball-roller comprising an independently rotatable, central section designed to operate on the door track, ballbearings, arranged. in circular ball-races formed concentrically in the'opp'osing faces of the roller-parts, and adjustable studs,

mounted in the bracket, on which the endballs sections of the roller are journaled axially.

In a'door hanger, the combination with a bracket, of a cylindrical roller comprising 15 located centrally to travelon the track of 110 g mimosa the 01001 frame, said segments being suit- In testimon whereof I afix my sig ature ably spaced apart and provided with ballin presence 0 two witnesses. bearings located between the opposing faces,
